To all whom it may concern:

.Be it knownthat 1, JOHN B. Ennmcn, a citizen of the United States,residing at Indianapolis, in the county of Marion and State of Indiana,have invented a new and useful Combination Stove and Gas-Range, of whichthe following is a specification.

It is the object of myinvention to provide a stove, and particularly acooking range. which can be used for either solid or fluid fuel. or forboth such fuels at once, and can easily be converted from a conditionfor using one ofsuch fuels to a condition for using the other or both,and vice versa.

The accompanying drawings illustrate my invention in a range for the useof coal and gas, though my invention is not limited to the use oftheseparticular fuels or in all of its. aspects to this particular kind ofstove. V

In these drawings, Figure 1 is a perspective view of a complete rangeembodying my invention; Fig. 2 is'a somewhat similar view showing thedoors open and some of the parts removed; Fig. 3 is a vertical sectionthrough the lower part of the range, substantially on the line 3-3-ofFig. 4, also showing some features not shown in'Figs. 1 and 2; Fig. 4 isa horizontal section on the line 4-4 of Fig. 3; Figs. 5 and 6 arevertical sections through the upper part of the range, one beingperpendicular to the front of the range and one being parallel thereto;Fig. 7 is a section on the line 7-7 of Fig. 5:- Fig. 8 is a section onthe line 3 88 of Fig. 6; Fig. 9 is a detail showing the mounting of theswinging brackets for the broiler; Fig. 10 is a view similar to Fig. 9.but showing a solid broiler bracket; Figs. 11 and 12 are verticalsections somewhat similar to Figs. 5 and 6 respectively. but showing amodified construction; and Fig. 13 is a horizontal section substantiallyon the line 1313 of Fig. 11.

The stove top 10 on which ordinary cooking is done is supported at thedesired height on le s 11. and is provided with a removable frame 12which carries the ordinary stove lids 13. Above the stove top 10 are arear wall 14 and side walls 15, surmounting hich is a shelf 16supporting the oven 17. The side walls 15 extend forward but part wayalong the sto e top 10. and sliding doors 18 are provided forcooperating with the walls 14 and 15 to inclosecompletely the spaceabove the rear part of the stove top 10 while leaving, the forward partopen,.as shown in Fig. 1, for lessenin the escape of heat or odors intothe room. I Jach door has a single roller.19, near its center to assistthe rollers in supporting the doors.

The stove top is conveniently divided into three sections, asillustrated, beneath which is the heating chamber. Below the centersection is located the fire pot 20, and below that is an ash box 21,such ash box being in the form of a sliding drawer mounted withmg acasing 22 inclosing such fire pot and ash box. The front ofthe fire boxis provided with a door 23, and the side of the casing 22 with a slidingdamper 24. The door 23 and the front of the drawer 21.n1ay also heprovided with draft-controlling devices if desired. Above the fire pot20.is detachably mounted a gas burner, which conveniently consists ofperforated gastubes 25 supported in holes 26 in the stove frame (seeFigs. 2 and 3) and controlled by gas valves 27. Below the side sectionsof the stove top are open spaces 28, which are the end sections of theheating chamber and are separated from the central section thereof abovethe fire pot and below the central section of the stove table by dampers29 operable by sliding rods v3(). The slidingdampers 29 are connected byrods .31 to swinging dampers 32 connecting the spaces 28 with verticalflues provided bv the rear wall 14 and a U-shaped partition to the frontof said rear wall. A swinging damper 32' operable by a rotatable rod 30'con- 3). such burners normallv being lowered (as shown at the right ofFig. 3i. To permit this SWlIlQlnQ of the burners 36. such burners areattached to members37 each having' a straight notch 38 and an anglednotcl '39 which respectively cotiperate with fixed ihs and 41 on therange frame, the mem ers- 37 also being providedwith operating halidles42, whereby the burners may be swung around the pivot pin 40 and slideither-dorward or backward to cause thaburner'; to'= be held u bv thepin 41 and the horizontal portion 0 the slot 39 or'to" be allowedF'to,drop by reason of the vertical portioig 0f s'ai slot. he accompanying"swinging, in the gas supply connection for these bui'ltiers' takes placein the mixers 37' so that 'no swinging joint is necessary. Renioiablymounted plates 36 may, be hung well below the end sections of theheating chamber; so that any sent or' greasewhich may drop through thetubes 28. when the plates 35 are removed will be caught. VVithin""-theflue 33 are mounted hot blast" supply (ibudu'its' 45, formed by Ushapedmembers attached to the rear face of the part 3 which conduits 45communicate with inlet gopenihgs 46 in the front of the p'artjiit andlwith horizontal conduits 47 extending forward Beneath the centralsection of the sto'i'e'top and above the fire pot. The inlet openings 46are controllable by hand valves 48 (one of which is shown removed inFist 2), and the conduits 47 are provided with lateral openings 49 whichdischarge heated air Sidewise a'nd downward on to the fire within thefire pot to assist combustion.

, The flue 33 extends past the rear edge of the shelf '16 to a partition50 aboveand spaced from said shelf. This providesahorizontal s ace orfl'uew50', which near its sidesis provided with forwardlv-extendinqbalile' partitions 51, and near its forward edge may be provided withbaffle tubes 52, which also serve another function to be pointed outlater. These bafi e platesand tubes compel products of combustionpassing up through the flue 33 to pass forward throu h the flue 50 andaround 'the edges of the balfle partidons-51mm fiues 53 extending upwardat the sides'of the oven' 17 to a horizontal flue 54 above such o en.this horizontal flue corriitiunica'ting with the stove-pipe or chimney55' extending upward from it. The front ends of t'h'' horizontal fluesj50 and 54 may be provided with removable doors 56, for cleaningpurposes. The batlle tubes 52 are open at the bottom, but at the top areprovided with. closing valves 57 carried by screws 58, so that thesetubes may be opened or clo'sedas desired. At the bottoms of the tubes 52are mounted fluid f'ue'l burners 59, shown as gas blirners, which aremounted to rotate about the axis of their fuel-supply pipes 60 sothatthey will, discharge either upwardly: as shown in Fig. 5. or downweirdlyas shown in Fig. 6. The upward discharge is used for heating the oven17, t "e vtilv'es'57 being open at this time, while t e dfiwnwaeddischarge is" for playing a flame, upon the upper surface of a broiler61- which is removably and adjustably sup- 'pivot rods 63, mounted insupports 64;

fastened to the range frame, and also have pins which may cotiperatewith holes in the supports 64, as shown in Fig, 9. By shifting thebrackets 62 endwise, the pins 65 are disengaged while the pins 63 remainin engagement with their coiiperating holes, thus permitting the bracketto be swung about the pins 63. This swinging is done automatically bysprings 66, which tend not only toswing the bracket 62 to horizontalposition, as shown in dotted lines in Fig. 6, but alsovto move thebrackets 62 endwise to bring the pins .65 into engagement with thecoperating holes in the bracket 64. Thus when the broiler is supportedon the brackets, as shown in Fig. 6, the brackets are held by thesprings 66 in the position shown in Fig. 9'; while upon the removal ofthe broiler 61 the'brackets 62 are pulled for- Ward slightly todisengage the pins 65 from their co'c'perating holes, whereupon thesprings 66 swing the v brackets to their horizontal position. Thepartition 34 at the rear of and abovethe broiler 61 is provided with asliding damper 68, so that the products of combustion from the burners59 when the latter are directed downwardly may pass out into the fine 33and upward through the lines 50, 53, and 54, and the smoke pipe. 55. Thedamper 68valso serves as a check-draft when coal is used as fuel. Abovethe partition 50 and within the oven 17 is ahorizontal partition 70,which provides between it and the partition 50 a space 71 closed at thefront and sides but open at the rear and at points above the valves 57;This causes the flames from the burners 59,'whcn such burners areupwardly directed, to pass around the edges of the valves 57 and to bedi erted back again into ran upward course, thus preventing such timesfrom coming forward against the oven door 72. The oven isprovided withthe usual oven shelves 73 adiustable to desired heights. At the top ofthe oven there is a horizontal space 74, provided by a partition 75 andthe roof 76 of the oven, and this space 74 is open at the front end tothe space within the oven, and at the rear end to a curved passageway77- which communicates with the horizontal fine 54. This space 74 ispreferably latcrallv contracted at its center portion, so that betterradiation from the flue 54 may be obtained when coal is used as a fuel.A suitably operated damper 78 may be provided for closing thecommunication between the space 74 and thepip k 79, which convenientlyconnects with allsuch burners.

When the range is 'used for coal, the burners 36 are swung down, theburners are removed, the plates 35 are put in place, the rods are pushedin to open the dampers 29 and 32 if the side sections of stove are to beused and pulled out if they arenot to be used and a concentrated heat isdesired on the center section, the damper rod 30' is turned to open thedamper 32" if the dampers 29 and 32 are closed. and usually to close thedamper 32 if the other two dampers mentioned are open, and the valves 57and the damper 78 and usually also the damper 68 are closed. The draftfor the coal fire in the fire pot 20 is controlled by the damper 24, theair valves 46, the damper 68, and even the doors 56 if necessary. Alsothe ash drawer 21 may be slid partly out to provide greater draft, ifdesired. The products of the combustion of the fire pass through theopening provided by the damper 32 or through the openings provided bythe dampers 29 and 32, into the flue 33, ascending theretniough to thehorizontal flue 50 and circulating around the baflle partitions 51 andballie tubes 52, passing thence into the side flues 53 on intothe'horizontal flue 54 above the oven escaping through the smoke pipeThis heats the stove top directly, and the oven by the passage throughthe fluee mentioned of the hot products of combustion, such fluespractically surrounding the oven. None of the products of combustion getinto the oven itself. Baflles 28 may be provided for compelling theseproducts of combustion to pass through all parts of the end sections ofthe combustion chamber.

When fluid fuel, such as gas, is used, the plates are removed, theburners 36 are swung up into operative position, the burners 25 are putin place, the dampers 29, 32, and 32 are usually but not necessarilyclosed, and cooking is done on thestove table in the ordinary manner ofgas stoves. If the oven is to be used, the burners 59 are directedupwardly and the valves 57 are open, as shown in Fig. 5, the damper 78also being opened to' allow the escape of the gas fume from the oven. Ifdesired, the gas heating of the oven may be used in conjunction with thecoal heating thereof'already described. When broiling is to be done thegas burners 59 are directed downwardly and the broiler 61 is hung on thebrackets 62 in proper position, the gas fumes escaping through the nowopen damper 68, and the valves 57 preferably being closed. If desiredthe brackets 62 may be made solid, as shown in Fig. 10, so that tyleaving the broiler in place and closing the doors 18 the fumes fromodoriferous cooking may be prevented from escaping into the room orentering the oven, even if the valves 57 are open, such fumes insteadbeing carried off through the hot blast conduits.

Instead of the construction of gas burner 59 and associated parts shownin Figs. 5, 6, and 7, the construction shown in Figs. 11, 12, and' 13may be used. The flues 33, and 53, and the battle partitions 51, aresubstantiallythc same as in the construction already described. However,in place of the circular battle tubes 52, I use a single rectangularinc'losing partition within the lower end of which are mounted tubularburners 81 instead of the circular burners 59 of the construction firstdescribed. The openings in the tubular burners 81 may be directed eitherupwardly or downwardly by turning these tubes about their axes. Theupper end of the opening through the partition' 80 is surmounted by avalve 82 supported on vertical sliding bars 3 working in slideways 8*carried by the partition 80. By sliding the rods 83 upward or downward,as by rotatable rods 85 connected to the bars 83 by rack and pinionconnections, the valve 82 may be made to open or close the upper end ofthe opening formed by the partition 80. the valve 82 being extended at.the sides and rear so that it also acts as a baflle plate to direct theflames from the burners 81 toward the sides of the oven when the oven isbeing heated by gas or other fluid fuel. and the valve 82 is thuscorrespondingly raised.

For cleaning the stove, the doors 56 are removed and the collected sootis scraped from the flue 54 into the side flues 53, the walls of theseside flues are scraped, the soot is scraped from the bottoms of the sideflues around the battle partitions 51 and then from the flue 50 into theflue 33, the bottom of which is provided with ,a hopper having aremovable door 91 discharging into the ash drawer. The shelf 50 at theupper end of the flue 33 may be provided with a removable door 92,through which a scraper may be inserted to scrape the'side walls of suchflue.
